Duration: 43 min
Bitcoin was created in 2009, a crypto currency that could be defined as virtual, unofficial money, that can be used as a means of commercial exchange. At first it could only be used on the Internet, but now it can be used in the “real world”. Bitcoin is generated through mining, each miner performs various tasks which are rewarded with bitcoin. This digital currency is the proof that cash tends to disappear, being replaced by new technology.
Anyone can mine bitcoin, transactions are anonymous, can be made 24 hours a day, every day of the year. Bitcoin is disruptive in our conception of money, since bitcoin is not controlled by any bank or country in the world. When dealing with banks, we have to respect times, rules and pay commissions in each transaction. Bitcoin is a fast, efficient and cheap payment system that came to speed up the use of money by making it more democratic for everyone.
